Swath-derived elevation and elevation change from CryoSat-2 over the Antarctic ice Sheet, 2011-2016
These files are gridded topography, rates of surface elevation change, and errors as 500m and 1km posting determined from surface elevation measured by swath processing of data acquired by the interferometric radar altimeter CryoSat-2. The gridded products cover the Antarctic Ice Sheet between 2011 and 2016. These data have been processed by the University of Edinburgh and are made publicly available as part of a European Space Agency funded project involving the University of Edinburgh, isardSat UK, University of Leeds-CPOM, ENVEO. Gridded elevation and elevation change over the CryoSat-2 LRM sector of the Antarctic Ice Sheet are provided by CPOM.

Methodology:
The gridded product have been generated from swath processing of CryoSat data, gridded using a regression accounting for time-dependant surface elevation change. The methodology is described in details in:
Gourmelen, N, Escorihuela, M, Shepherd, A, Foresta, L, Muir, A, Garcia-Mondejar, A, Roca, M, Baker, S & Drinkwater, MR 2017, 'CryoSat-2 swath interferometric altimetry for mapping ice elevation and elevation change' Advances in Space Research. DOI: 10.1016/j.asr.2017.11.014
Data collection:
CryoSat-2 spaceborne interferometric radar altimeter.
Data quality:
Validation against operation ice bridge airborne laser altimeter returns a mean difference of 0.8 m, a median difference of 0.3 m, a standard deviation of 75.4 m and a median absolute deviation of 2.8 m.
